HVAC Accessories 20mm Flange Duct Corner

Product Introduction:

A 20mm Duct Corner is a compact, L-shaped metal fitting used to connect the corners of small-to-medium-sized rectangular ducts in HVAC systems. With a corner size of 20mm, it is typically used in light-duty air ducts, modular ventilation units, or tight-space installations where larger corners may not fit.

20mm Duct Corner core functions include:

1. Structural stability: Providing connection points for air ducts through precise dimensions and shapes to prevent displacement caused by vibration or external forces.

2. Sealing: Improve the sealing of system connections, reduce air leakage, and ensure ventilation efficiency.

3. Adaptability: Supports flexible combinations of different pipe diameters or angles to meet the installation needs of complex building spaces.

What Problems Does a 20mm Duct Corner Solve?

• Fits Tight Spaces: Perfect for small or compact duct systems where larger corners don’t fit.

• Lightweight Support: Provides strong corner reinforcement without adding bulk or weight.

• Improves Air Tightness: Ensures secure flange connections to reduce air leakage.

• Speeds Up Installation: Easy to install, saving time and labor costs.

Typical Applications of 20mm Duct Corner

• Compact HVAC Systems – Small-scale ventilation units in tight mechanical spaces

• Modular Air Handling Units (AHUs) – Lightweight, pre-fabricated systems

• Retrofitting Projects – Where space is limited and components must be low-profile

• Electronics Cooling Cabinets – Compact ducting for precision cooling

• Cleanroom Equipment – Mini duct systems in controlled environments

• Mobile or Temporary Installations – Such as exhibition HVAC, mobile labs, or shelters
